LED Jellies Lamp Stand 

Written By: Matthew de Venecia 



f TOOLS: 

• Hot glue gun (1) 
( with glue) 

• Ruler (1) 

• Soldering iron or electrical tape (1) 

use safety precautions, wear safety gear 
for eyes and hands while handling a 
soldering iron. 

• drill with drill bits (1) 

• wire stripper or pocket knife (1) 



© PARTS: 



wooden board, (1) 

must be at least 5 inches long. 3 inches 

wide, and 1 inch tall 

sturdy wooden or metal pole (1) 

toy bubbles (from a vendor) (2) 

you can do this project with one, but the 

circuitry would be slightly different 

insulated copper wire (1) 

I'd recommend 16 gauge, at least I think 

that's what I used..... 



i • LEDs (4) 



Thumbtack (1) 

moldable casein (1) 

must perform milk to plastic experiment 

(heat 1cup of milk, add 4 teaspoons of 

white vinegar, and a pinch of corn 

starch. Stir then strain casein out with a 

strainer) 

9 volt battery (1) 

kabob stick (1)

popsicle stick (1) 

uninsulated copper wire (1) 
about 30 gauge 



SUMMARY 

This is a modification of the LED jellies contributed by Angela Sheehan . For design 
instructions for jellies, check out Angela's project . 

For this project you will need to know how to use a soldering iron, a hot glue gun, and a drill 
WARNING: Do not multitask with these tools! They can be very dangerous! 




• Use the thumbtack to poke 2 holes in each of the toy bubbles about 3/4 of a centimeter 
apart. 

• Solder the two LEDs together. Take one of the LED's negative terminals (shorter leg) and 
solder it to the other LED's positive terminal (longer leg). 

• Repeat using the other two LEDs. 

• Bend the soldered terminals upward so that the LEDs will be able to fit into the toy 
bubbles. 

• Insert the unsoldered terminals into the holes you made in the toy bubbles.

• Measure out V of the insulated 
copper wire and cut it off. Repeat 
this once more. 

• Measure out about 3 more inches 
of the copper wire and cut it off. 
Repeat this once more. 

• You now should have two V pieces 
and two 3" pieces of insulated 
copper wire. Make sure you do. 

• Cut off the insulation at the ends 
using a wire stripper or a pocket 
knife. 





• Solder one of the V wires onto the 
negative terminal of an LED that 
was inserted into the toy bubble. 

• Solder one of the 3" pieces onto the 
same negative terminal. 

• Solder the other end of the 3" piece 
onto the negative terminal of 
another LED in a different toy 
bubble. 

• Mark the unsoldered end of the 1' 
wire, showing that the wire is 
attached to the negative terminals 
(LED's won't work if you connect 
the ends to the wrong battery 
terminal).

• Solder the other V wire onto the 
positive terminal of an LED that 
was inserted into the toy bubble. 

• Solder the other 3" piece onto the 
same positive terminal. 

• Solder the other end of the 3" piece 
onto the positive terminal of 
another LED in a different toy 
bubble. 

• Hook the 9V battery on to the 
positive and negative 1' wires to 
see if the circuitry works. If not, 
make sure you are inserting the 
wire connected to the LEDs into the 
correct battery terminals. If it still 
doesn't work, check over these 
steps to see if you have done 
something wrong.

• Use the casien from the milk-to- 
plastic experiment to create two 
small walls about the size of the 
ends of the 9V battery. 

• Cut off two 1cm strips of 
uninsulated copper wire. 

• Insert the strips into the casein so 
that they will be able to touch the 
terminals of a 9V battery. Wait for 
the casien to dry. 



Step 6 




• Make the lamp stand by drilling a 
hole into a block of wood and 
inserting a sturdy one-foot pole into 
it, then hot-gluing it into place. 

• Hot-glue the hardened casein onto 
the lamp stand, but make sure that 
a 9V battery can fit from end to end 
between the 2 pieces. 

• Hot-glue the 2 LED toy bubbles 
close to the top of the one-foot 
pole, making sure the one-foot 
wires are able to touch the bottom 
of the lamp stand (you may want to 
decorate them as jellyfish first, 
though).

• Solder one of the ends of the V wire pieces connected to the LEDs to one of the strips of 
uninsulated copper wire in the casein. 

• Snap 1/2 of a centimeter off of the popsicle stick and hot-glue it a centimeter away from 
the unsoldered strip of uninsulated copper wire in the casein. 

• Hot-glue the remaining end of the 1' wire piece to the 1/2cm popsicle stick piece while 
getting the end of the wire as close as possible to the uninsulated copper wire strip without 
having them touch.

Divide the remainder of the popsicle stick into 3 even pieces. 

Drill 2 holes into one of the pieces, one in the top right corner and one in the middle-left of 
the piece. Repeat this on another popsicle stick piece. 

Drill a hole in the top of the remaining piece. 

Cut two 1cm pieces off the shish kabob stick and insert them into the holes in the identical 
popsicle stick piece. 

The popsicle stick piece with one hole goes with the shish kabob stick piece that was put 
into the top right corners of the other popsicle stick pieces.

• Cut off 3" of uninsulated copper wire and mash it into an "under-over" pattern so it's about 
the size of a fingernail. 

• Cut a slit into the popsicle stick piece with one hole. Also, hot-glue the mashed up copper 
wire into the slit. 

• Hot glue gun the popsicle stick pieces to the lamp stand base so that the mashed up 
copper wire is able to touch the end of the wire piece and the uninsulated copper wire in 
the casein at the same time. 

• Connect the uninsulated copper wire pieces in the casein to the correct terminals on the 
9V battery. 

• Flip the make-shift popsicle switch system on (to do that, make the mashed up copper 
wire pieces touch the end of the V wire and the uninsulated copper wire in the casein). 

• Decorate your new jellyfish lamp (see LED jellies contributed by Angela Sheehan ).
